Non-Negative Least Squares

Track zeolite crystallization with a practical Python tutorial on spectral unmixing

Zeolite crystallization is notoriously hard to track in real time. This tutorial shows you how to do it with spectral unmixing and real in situ data, using Python from start to finish. The approach is practical and reproducible, no black boxes, just non-negative least squares modelling applied to Raman spectra. If your spreadsheet memory keeps spiking on large data loads, you might also appreciate why streaming solves that problem.
